Undo (Ctrl+Z)

Undoes the last action to the map. The description of the item to be undone is in the Edit menu, and also is displayed if you hover the cursor over the undo button. The number of levels you can undo is controlled in the Settings dialog. Unlike many other programs, saving a file does not erase the undo history. You can still undo to actions that took place before you saved.

Redo (Ctrl+Y)

Redoes the last undo. Like undo, the Edit menu and redo button's hint both display the action that will be redone. The redo history is erased as soon as you make a change to the map (that is, once you add/delete/change an object, you cannot redo a previous action).
